10 Sept. 82.
Verehrtester Herr College!
Zunächst empfangen Sie meinen besten Dank für die Übersendung Ihrer Photographie u. die Fortsetzung Ihrer "Fragmenta phytogr. austral." dessen 11ter Band, wie alle frühern ein abermaliges Zeugniss Ihres grossen Fleisses nach allen Seiten der Wissenschaft ablegen.
Die beiden Algen, welche Sie mir in dem Briefe vom 6 Juni übersandten, habe ich erst vor Kurzem untersucht u. bestimmt. Dieser Brief u. die andern Sachen kamen gerade in den grossen Ferien hier an, welche ich sonst zu wissenschaftlichen Arbeiten benutzt habe, diesmal aber war ich auswärts bei meinen verheirateten Kindern zu Besuch u. nach den Ferien kamen sie theilweise selbst hieher zu Besuch u. da war an mikroskopische Untersuchungen nicht zu denken. Also die beiden Algen sind:
die an Mangrovewurzeln:

Es scheint mir als wenn bei Ihnen in Südaustralien auch alle unsere Süsswasseralgen vorkämen. Ich habe schon verschiedene derartige durch unsern seel. Sonder bekommen u. sollten Sie noch mehr haben, oder künftig noch sammeln, so würde es mir eine wahre Freude sein, sie zu bestimmen. Vielleicht benutze ich noch einmal diese Sachen dazu einen Vergleich Ihres Süssawasseralgen mit unsern Deutschen zu bearbeiten u. in einem künftigen Osterprogramm unseres Real-Gymnasiums erscheinen zu lassen. Ich bin in diesen Sachen noch so zu Hause, dass mir die Bestimmung keine besondern Schwierigkeiten macht. Im Übrigen glaube ich auch, dass mir, trotz meiner 75 Jahre, doch noch einige Jahre zu leben vergönnt sein wird.
Indem ich nun hoffe u. wünsche, dass diese Zeilen Sie recht wohl und munter antreffen mögen, zeichne ich mit den freundlichsten Grüssen als
Ihr
ganz ergebenster
Kützing.

Most esteemed colleague,
Firstly, receive my warmest thanks for sending your photograph and the continuation of your "Fragmenta phytogr. austral.", of which the 11th volume like all the previous ones once more bears witness to your great diligence in all branches of science.
I have only recently examined and determined the two algae that you enclosed with your letter of 6 June. That letter and the other things arrived here during the long holidays that I have usually used for scientific work, but this time I was away visiting my married children, and after the holidays some of them came to visit here and microscopic examinations were out of the question.
Now, the two algae are:
the one on mangrove roots:

It seems to me that all our freshwater algae also occur with you in South Australia. I have already received various ones of them through our late Sonder, and if you should have more, or collect more in future, it would be pure joy to me to determine them. Maybe I shall use these things some time to work up a comparison of your freshwater algae with our German species and publish it in a future Easter programme of our High School. I am still so much at home in these things that determination does not pose any particular difficulties. In addition I believe that in spite of my 75 years a few more years of life will still be granted to me.
While I hope and wish that these lines may find you well and happy, I sign with sincerest regards as
Your very devoted
Kützing.
